MACHINE FOR MANUFACTURING BRIQUETS.

Specification of Letters Patent.

Patented Nov. 14, 1905.

Application filed June 26, 1905. Serial No. 267,038.

To all whom, it may concern.-

Be it known that I, GOTTFRIED HoPFNER, a subject of the King of Prussia, German Emperor, and a resident of Ohausseestrasse 12, Bleckendorf, Province of Saxony, Germany, (whose post-oflice address is Ohausseestrasse 12, Bleckendorf, Province of Saxony, Germany,) have invented certain new and useful Improvements in and Relating to Machines for Manufacturing Briquets; andl do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

The present invention relates to machines for making briquets, and has for its object to continuously operate and to discharge the briquets onto a carrier timed to operate from a moving part of the machine; and it consists of the construction and arrangement of parts hereinafter described and claimed.

Referring to the drawings, in which like parts are similarly designated, Figure 1 is a longitudinal section with parts shown in elevation. Fig. 2 is a side view. partly in section. Figs. 3, 4, and 5 are plan views of the mouthpiece insertions or forms it. Figs. 6 and 7 are details.

The machine consists of a mixing apparatus in combination with a molding-machine provided with a device timed to out off the material as it emerges from the mouth or with suitable mixer-blades 0.

On the shaft 10 is mounted a bevel-gear 12, driven by a bevel-pinion 13, on whose shaft 14: is mounted a belt-pulley 15 to drive the mixer-blades.

These blades mix the material and during the mixing move it through the cylinder 6 toward its discharge-opening 16, the size of which is controlled by slides d (1, one on each side of the cylinder 6, each operated by a screw-spindle l7 and hand-wheel 18, Fig. 2, thereby regulating the quantity of material delivered from the mixer to the molder.

The molding device consists of a vertical cylinder d, provided with a gradually-contracting mouthpiece or nozzle f, in which is mounted a conveyer-worm 6, Ol1 the end of whose shaft is a bevel-wheel 19, driven by a bevel-pinion on a counter-shaft a, mounted in the frame of the machine. 21 is afast and 22 is a loose driving-pulley mounted on shaft 02.

The mouthpiece f is provided with pipes g to supply water to the material as it is forced through the nozzle f, thereby preventing the material from sticking to the sides and to the insertion-pieces 7t, Figs. 3, 4, and 5, the moistening of the material just as it leaves the machine giving the briquets a smooth glazed appearance.

On one end of shaft a is a cone-wheel 0, and below this wheel is a shorter shaft a, mounted in bearing a on the frame of the machine. A second cone-wheel 0 having a belt disk or pulley 19 cast thereon, is loosely mounted on the short shaft rand capable of being connected thereto by the coupling-clutch q A step-pulley s is keyed to the shaft 0*,

which also carries the controller-disk m, carrying two adjustable pins 0 and 0 The pin '0 contacts with the lever O, Fig. 7 mounted on rod N, that carries the actuating-rod F for one of the two knives DD, that are moved to and from each other and guided in slideways M of angle-irons mounted at the bottom of the mouthpiece f.

The lever O has pivoted to it at 24 one end of a connecting-rod R, whose opposite end is connected to the end of the shorter arm of lever Q, mounted on a pin 23, secured to the mouthpiece or nozzle f. The end of the longer arm of this lever Q is connected to the end of a connecting-rod R, similar to the one R, the other end of said rod R being connected at 25 to the end of lever O, keyed to the rod N, on which is rigidly mounted the lever F, similar to the lever F, and which operates the other knife D. The lever F is urged by a spring S, connected to a suitable stationary part and here shown as the casing (Z of the molder The pin 1: on disk m engages the lever 20, pivoted at 26 on the frame.

The lower end of lever w is connected by rod to an elbow-lever carrying a weight B on one arm and a pawl 2 on the other arm, that operatesaratchet-wheel A. The ratchetwheel A is rigidly mounted on a drum Z, over which travels a conveyer-band Z, said drum being mounted in a suitable standard 28. A similar drum Z is adjustably mounted in the standard 27, so as to be able to take up any slack in the band Z.

On the band rest suitable gratings it, onto which the briquets are deposited during the step-by-step movement of the band, so that the grids with the briquets thereon can be taken off from the end of the band at the drum l and other gratings placed on it at the beginning thereof near the drum Z.

Beneath the cone- Wheel 0 and its bandpulleyp is a stepped'pulley t, mounted on a stub-shaft 9.9 on the frame, so that 19 may be belted to t and t belted to .s' to further reduce the speed of disk m, and thereby make thicker briquets, if desired.

If cone-wheel 0 be bolted to the cone-pulley 0 so that the belt will be on the largest diameter of 0 and on the smallest diameter of 0 the controller-disk m will make its greatest number of revolutions, and ifv the belt be shifted to the opposite ends of these pulleys the speed will be less, it of course being understood that the clutch holds the conewheel 0 locked to the shaft 0.

Should it be desired to have a further reduction of speed, the coupling q is disengaged, so that cone-wheel 0 can run free, and the wheelp on the end of the cone-wheel 0 is belted to the larger step on the pulley t and the smaller step on pulley t is belted to the wheel 3.

The insertions or molding ends it may be of various forms, as shown in Figs. 3, 4c, and 5, and can be rapidly changed so as to change the form and size as desired, the thicknesses being regulated by the speed of the controllerdisk m. When the speed of this disk is greater, a shorter string will have been forced through the nozzle f, to be cut off by the knivesD D, actuated by the pin o than when the speed is slower. Altering the speed of the disk also alters the periods of progression of the carrier.
